Abstract
The invention discloses a clad type combined hot nozzle. The clad type combined hot nozzle comprises a hot nozzle main body, an alloy sleeve assembly and a heating wire. A runner hole is formed in the hot nozzle main body in the axis direction of the hot nozzle main body, and the alloy sleeve assembly is arranged in the runner hole. A heating wire groove is formed in the hot nozzle main body, and the heating wire is embedded into the heating wire groove. The alloy sleeve assembly comprises a heat-conduction copper sleeve and a runner sleeve. The outer wall of the heat-conduction copper sleeve is attached to the inner wall of the runner hole. The runner sleeve is arranged in the heat-conduction copper sleeve. The outer wall of the runner sleeve is attached to the inner wall of the heat-conduction copper sleeve. In this way, the hot nozzle main body is high in strength and high in heat conduction speed; heat is transferred in a balanced manner; the runner hole is quite hard and resistant to corrosion and abrasion; and the hot nozzle is great in bending resistance and long in service life.
Description
Technical field
The present invention relates to Re Zui field, particularly relate to a kind of clad type and combine hot mouth.
Background technology
In prior art, hot mouth main body is integral type, having heaters embedded groove on external diameter, and heater is directly embedded into hot mouth master
In body groove, due to power and the length limitation of heater strip, it is difficult in whole hot mouth main body heater strip on the densely covered row of equilibrium, conventional
Way is all that close centre, two is dilute, and so, hot mouth is the longest, and the number of turns that middle heater strip is wound around is the fewest, and intervening gaps is more
Far, in the middle part of hot mouth main body runner, heat is difficult to pass over, and causes runner middle portion temperature on the low side, and plastics easily cool down, flowing speed
Degree is slow, is even difficult to flowing, causes adapted to injection system pressure high, and plastic emitting has some setbacks, and product has aberration, and flow liner etc. is bad.Impact
The Forming Quality of product.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of clad type and combines hot mouth, and intensity is high, and heat-transfer rate is fast, heat
Amount transmission equilibrium, runner hole is very rigid, anticorrosive anti-wear, and hot mouth warping resistance ability is strong, and service life is long.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of clad type to combine hot mouth,
Including: hot mouth main body, alloy sheath assembly and heater strip；Runner hole is had along hot mouth main body axis direction in described hot mouth main body,
Alloy sheath assembly is arranged in runner hole；Having heater strip groove in described hot mouth main body, heater strip is embedded in heater strip groove；Described
Alloy sheath assembly includes heat conduction copper sheathing and flowing channel sleeve, heat conduction copper sheathing outer wall and the laminating of runner hole inwall, and flowing channel sleeve is arranged on heat conduction
In copper sheathing, the outer wall of flowing channel sleeve is fitted with heat conduction copper sheathing inwall.
Preferably, one end, described runner hole has hot mouth sealant cover screw thread, and the runner hole other end is provided with step；Described alloy
Grip assembly one end is against on step, leaves one end distance between the alloy sheath assembly other end and hot mouth sealant cover screw thread.
Preferably, described hot mouth main body is high-carbon steel hot mouth main body, and described flowing channel sleeve is high hard wearable hard alloy set.
The invention has the beneficial effects as follows: the present invention hot mouth main body intensity is high, heat-transfer rate is fast, heat transmission equilibrium, runner
Hole is very rigid, anticorrosive anti-wear, and hot mouth warping resistance ability is strong, and service life is long.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of clad type of the present invention combination hot mouth one preferred embodiment.
In accompanying drawing, the labelling of each parts is as follows: 1, hot mouth main body；2, heat conduction copper sheathing；3, flowing channel sleeve；4, hot mouth sealant cover spiral shell
Stricture of vagina；5, runner hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of clad type combines hot mouth, including: hot mouth main body 1, alloy sheath assembly and heater strip, hot mouth main body 1 is high-carbon steel heat
Mouth main body；Having runner hole 5 along hot mouth main body axis direction in described hot mouth main body 1, alloy sheath assembly is arranged in runner hole；
Having heater strip groove in described hot mouth main body, heater strip is embedded in heater strip groove；Described alloy sheath assembly includes heat conduction copper sheathing 2 He
Flowing channel sleeve 3, flowing channel sleeve 3 is high hard wearable hard alloy set, and heat conduction copper sheathing 2 outer wall and the laminating of runner hole 5 inwall, flowing channel sleeve 3 sets
Putting in heat conduction copper sheathing 2, the outer wall of flowing channel sleeve 3 is fitted with heat conduction copper sheathing 2 inwall.One end, described runner hole 5 has hot mouth sealing
Lid screw thread 4, runner hole 5 other end is provided with step；Described alloy sheath assembly one end is against on step, the alloy sheath assembly other end with
One end distance is left between hot mouth sealant cover screw thread.
Flowing channel sleeve outside and heat conduction copper sheathing internal engagement, the alloy sheath assembly of composition copper covered steel, then, by limit height
Temperature technique loads the alloy sheath assembly of copper covered steel in hot mouth main body endoporus, becomes set in a three-piece with hot mouth body combination
Overall structure, the advantage of structure is, flowing channel sleeve is hard alloy sleeve, and hardness is high, and wear resistance is good, and corrosion resistance is strong,
Hardness is 1.5 times of high-carbon steel hot mouth main body, and antiwear anti-corrosion performance is 3 times of high-carbon steel hot mouth main body；Heat conduction copper sheathing
Heat conduction ratio is 3 times of high-carbon steel, and heat-transfer rate is fast, and heat conduction equalizes the problem that can solve cold two feverish sensation in the head in hot mouth runner stage casing；High-carbon
Having heater strip groove in steel hot mouth main body, heater strip embeds in main body, better than split heating mantle intensity, heater strip most diameter with
Body groove coordinates, and absorbent body heat is many, and the thermal efficiency is high, energy-conserving and environment-protective；Combined by this three-piece clad type, heat
Mouth main body intensity is good, and heat-transfer rate is fast, and heat transmission equilibrium, runner hole is very rigid, anticorrosive anti-wear, hot mouth warping resistance energy
Power is strong, and service life is long, and this structure solves at one stroke, and easily ftractureing during single steel grade bulk hardness height fractures, when hardness is low
Being easily bent deformation, the most wear-resistant being weak to is corroded, the problems such as heat conductivility is poor, and the thermal efficiency is low.Alloy steel bushing, heat conduction copper sheathing is whole
Using standard regulation gauge material, stock utilization is high, and production technology is simple, and after batch production, low cost, hot mouth finished product adds
Price is high, and profit margin is big.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
The equivalent structure that bright description and accompanying drawing content are made, or directly or indirectly it is used in other relevant technical fields, the most in like manner
It is included in the scope of patent protection of the present invention.
